Mansfield, Mass. - Datel's new LSM-10A Series, 10 Amp, non-isolated, POL (point-of-load) DCDC's are the epitome of modern power converters. They have the standard 6-pin SMT form factor. They are shipped in standard tape-and-reel packaging for high-speed automatic asssembly onto mother boards. They are assembled lead-free, and they can be attached to mother boards using lead-free solder.

Furthermore, LSM-10A's boast the lowest published prices ($9.95 USA each for 10k pieces) of any comparable 10A DC/DC converters, and they can be ordered over the internet and shipped anywhere in the world the next day. Someday, all DC/DC's will be this way.

Complete Selection in Standard Packages
The new 10A models of Datel's LSM Series offer input voltage ranges centered around 3.3V (3.0-3.6 range), 5V (4.5-5.5V) or 12V (10.8-13.2V). Nine output voltages (0.8, 1, 1.2, 1.5, 1.8, 2, 2.5, 3.3, and 5 Volts) enable the 24 models in the Series to address virtually all contemporary applications. LSM-10A's use the de facto SMT package standard. They are small (1.3 by 0.53 by 0.34 inches, 33 by 13.5 by 8.6 mm) and offer on/off-control, output-sense, and Vout-trim functions.

Lead-free SMT with Heat Shield
LSM-10A Series DC/DC's fall under the Datel Lead-Free Initiative. The program eliminates all lead from our printed-circuit boards (pcb's) and from our assembly and pinning processes. LSM-10A pcb's have an electroless nickel/immersion gold (ENIG) finish (instead of traditional solder), and the package pins are tin-plated copper.

The surface-mount LSM-10A's all carry high-temperature, plastic heat shields. The heat shields (to be removed and discarded or recycled after assembly) maintain a 50&degC differential between the LSM-10A's SMT components and the hot circulating air of a reflow oven. Consequently, the LSM-10A's, which are assembled using high-temp (+200&degC) lead-free solder, can be attached to a user's board with the same lead-free solder.

The Feature Set
Additional performance features of LSM-10A's include tight line/load regulation (&plusmn0.1%/&plusmn0.25% max.), quick step response (100μs), stable no-load operation (for load circuits going into "sleep" mode), and the ability to start-up monotonically and operate without incident into a pre-biased load. LSM-10A's also feature output current limiting and full short-circuit protection (hiccup mode with auto recovery).
